I've owned Emotiva monoblocks and have an XPA-5 gen 2 in my bedroom system powering the center and surround speakers. I've owned the A23 (not +). I think there's some snobbery in this thread. The Emotiva are not as bad nor is the Parasound as great as some are claiming. The difference between them isn't huge, but I'd go for the Parasound, it will be more refined. It doesn't look like those speakers are hard to drive? Why do you think you need more power?
